This kit contains 12 Cubelets that can be snapped together to make an endless variety of robots with no programming and no wires. Anyone can build robots that drive around on a tabletop, respond to light and other objects, and have surprisingly lifelike behavior. Instead of programming that behavior, you snap the Cubelets together and watch the behavior emerge like with a flock of birds or a swarm of bees. Each Cubelet has a tiny computer inside of it and is a robot in its own right. When you put Cubelets together, you're actually making a robot out of several smaller robots. Each Cubelet communicates with its neighbors, so you know that if two blocks are next to each other, they're talking.

Recommend 1 pack per student (or per team of 2 or 3 students) - and also purchase 20 pack to share between several teams.
